And in the meantime even 0.7.2 is out.
So retrying with Cassandra 0.7.2. Findings so far:
- With cassandra 0.7.2 bootstrapping the seconds node (replication factor 1)
works fine. No data is removed anymore and when I create users on node 1, they
appear on node 2 and visa versa. So bootstrapping and rep factor 1 seems to
work fine now.

> Key: AMDATU-254
> URL: http://jira.amdatu.org/jira/browse/AMDATU-254
> Project: Amdatu
> Issue Type: Bug
> Components: Amdatu Cassandra
> Affects Versions: 0.1.0
> Reporter: Ivo Ladage - van Doorn
> Assignee: Ivo Ladage - van Doorn
> Fix For: 0.2.0
>
>
> The following use case causes random data to disappear from the cassandra
> storage:
> - Start a node in the cassandra cluster with replication factor 1
> - Start another node in the cassandra cluste, also with replication factor 1
> Now apparently, bringing up the second node in the cluster causes random data
> to be removed from the Role ColumnFamily. After bringing up the first node,
> these are the row keys available in the CF 'Role';
> (1) user_marior
> (2) user_janed
> (3) group_Parent
> (4) user_melissad
> (5) group_Student
> (6) group_Administrators
> (7) user_georged
> (8) user_tedb
> (9) group_Teacher
> (10) user_elisad
> (11) user_Administrator
> (12) user_maijam
> (13) user_johnd
> After booting the second node, random data disappeared:
> (1) user_marior
> (2) group_Teacher
> (3) user_elisad
> (4) user_Administrator
> (5) user_maijam
> (6) user_johnd
> the result is different every time you try it. Also, when I stop node 2,
> clean its cassandra database and start it again, more data is missing.
